Weaning Kimberley Cattle Pays Off, D Pratchett, Stuart Young
Weaning Kimberley Cattle Pays Off, D Pratchett, Stuart Young
Journal of the Department of Agriculture, Western Australia, Series 4
Research results show that weaning Kimberley calves when they reach 140kg liveweight is one way of increasing herd productivity by changing management practices. However, removing the bulls from the breeding herd, rather than running them with the cows ywear round as is the practice, does not increase branding percentage.

Feedlots For Beef In W.A. : Some Guiding Principles, D J. Barker
Feedlots For Beef In W.A. : Some Guiding Principles, D J. Barker
Journal of the Department of Agriculture, Western Australia, Series 4
FEEDLOTS are small enclosures where all of the animal's feed is supplied from an outside source. Compared with grazing, feedlotting is an expensive method of beef production.
This article gives a guide to the requirements for establishment and management of a farm feedlot, especially the basic equipment and materials, the type of cattle most suited to feedlotting, rations and feeding techniques.
The author warns that skill and experience are needed to run a feedlot and describes feedlotting as an expensive method of beef raising when compared with grazing.

When Is A Cattle Feedlot Profitable?, J T. Stoate
When Is A Cattle Feedlot Profitable?, J T. Stoate
Journal of the Department of Agriculture, Western Australia, Series 4
THE current surge of interest in feedlots stems from low coarse grain prices and comparatively low early summer baby beef prices. Cattle raisers sense the opportunity for higher prices by holding the cattle on the farm over summer and autumn, and grain producers see better returns from barley and oats fed to cattle than sold as grain.
This article examines the profitability of cattle feedlots and presents sample budgets for two typical situations—the farmer who produces his own cattle but buys grain, and the cereal grower who produces grain but buys in cattle for finishing in a feedlot.

The October, 1970, issue of the Journal of Agriculture included results from the first year of a dairy beef production trial at Bramley Research Station.
This report presents results from the trial's second year, during which two levels of pasture utilisation were tested. The trial is now in its third year.
Thinking Of Pigs To Raise Your Income?, P Mcnamara
Thinking Of Pigs To Raise Your Income?, P Mcnamara
Journal of the Department of Agriculture, Western Australia, Series 4
WHEAT quotas and low wool prices have caused many farmers to look to pigs to consume homegrown grain and to lift their incomes. However, with sow numbers at a record level, is it possible for a wheatbelt farmer to raise pigs profitably?
Because of his access to cheap grain, the wheatbelt farmer may be able to make a good profit on each pig sold. This could make pigmeat production a useful sideline on the farm, providing the farmer produces only lean pigs. There is no market for overfat pigs.
This article gives some hints on production of pigs on cereal …
Three Beef Raising Systems For Butterfat Producing Properties, Department Of Agriculture, Western Australia
Three Beef Raising Systems For Butterfat Producing Properties, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
THREE-QUARTERS of the calves born in autumn on butterfat farms are not required as milking replacements and are thus available for beef production or immediate sale, at about $20 a head.
The profit from selling beef must be compared with that from selling excess calves off their mothers.
Such a comparison is being made by Department of Agriculture Beef Research Officer D. J. Barker in a series of trials at Bramley Research Station, Margaret River.
High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter
High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter
Journal of the Department of Agriculture, Western Australia, Series 4
Analysis of lambing trials with Merino ewes has shown a highly significant association between pre-mating liveweight and lambing performance.
With May-June lambing ewes there was a 2.9 per cent, lambing increase for every extra 10 lb. liveweight; for July-August- September lambing ewes there was a 6.9 per cent, increase for every 10 lb. liveweight increase.
With the May-June lambing there was a critical weight below which twinning was negligible.

Journal of the Department of Agriculture, Western Australia, Series 4
STOCKING rates on dairy farms are generally too low and can be substantially increased, but unfortunately there is no satisfactory measurement to indicate the potential of a particular pasture or environment.
A trial carried out on Denmark Research Station in 1966-67, to obtain information on carrying capacity of a dryland kikuyu-subterranean clover pasture.
High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan
Journal of the Department of Agriculture, Western Australia, Series 4
KIKUYU is one of the most valuable pasture plants on dairy farms in the South-West of Western Australia.
It combines well with subterranean clover and ryegrass if heavily stocked, and pastures managed in this way can be cut for legume-grass hay in the spring. However, relatively little is known of its carrying capacity or potential for production under grazing.
A Comparison Of Methods Of Urea Application At Ajana, M G. Mason, R. J. Parkin, H. Patrick
A Comparison Of Methods Of Urea Application At Ajana, M G. Mason, R. J. Parkin, H. Patrick
Journal of the Department of Agriculture, Western Australia, Series 4
Compared with urea application separate from the seed, urea mixed with wheat seed delayed and reduced wheat germination, and reduced wheat yields, especially at high rates of urea.
Yields were higher where the urea was topdressed immediately before seeding than where it was top-dressed either immediately after, or two weeks after seeding.
Maintenance Phosphorus And Sulphur For Pastures : Progress Report, Walter Jacob Cox
Maintenance Phosphorus And Sulphur For Pastures : Progress Report, Walter Jacob Cox
Journal of the Department of Agriculture, Western Australia, Series 4
PASTURE IMPROVEMENT has been based on topdressing with superphosphate, which supplies sulphur as well as phosphorus.
In the past, all the benefit due to superphosphate was attributed to the phosphorus.
It is only in recent years that the importance of the sulphur has been appreciated.
West Midlands Development : Fertilizers For The West Midlands, Department Of Agriculture, Western Australia
West Midlands Development : Fertilizers For The West Midlands, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
FARMING the light lands of the West Midland area would be impossible without fertilisers.
Most light land areas are inherently very low in phosphate and also require nitrogen.
The nitrogen can come from fertiliser for cereal crops, or can be built up by growing appropriate legume pasture plants such as clovers and lupins.
West Midlands Development : Cereals For The West Midlands, Department Of Agriculture, Western Australia
West Midlands Development : Cereals For The West Midlands, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
THE sandplain soils and climate of the West Midlands area are primarily suited to grazing.
However, the place of cereals is receiving a great deal of attention in view of their advantages in the early stages of development, and the need for the diversification of farm production.

Rates Of Superphosphate For Pasture And Crop Production In The Salmon Gums District, R N. Glencross, W. J. Cox
Journal of the Department of Agriculture, Western Australia, Series 4
DURING the last few years large areas have been released for cereal and pasture production in the southern part of the Shire of Dundas and the northern part of the Shire of Esperance.
Changes in land use since 1962 are summarised in Table 1.
Rates Of Superphosphate For Cereal Grain Production In The Under 20 Inch Rainfall Areas, Walter Jacob Cox
Rates Of Superphosphate For Cereal Grain Production In The Under 20 Inch Rainfall Areas, Walter Jacob Cox
Journal of the Department of Agriculture, Western Australia, Series 4
EVERY year farmers use large quantities of superphosphate with cereal crops to overcome the inherent phosphate deficiency of West Australian soils.
The increase in the average rate used by farmers reflects the increasing amount of new land being cropped.
Good seasons and favourable economic conditions may also have influenced super rates.
Fertilisers For The Wheatbelt, William John Toms
Fertilisers For The Wheatbelt, William John Toms
Journal of the Department of Agriculture, Western Australia, Series 4
A review of fertiliser research findings and recommendations for fertiliser applications to crops and pastures in the 12 to 15 inch rainfall areas.
NOT long ago, fertiliser to the cereal grower meant only superphosphate for cropping. Today, phosphorus, sulphur, nitrogen, copper, zinc and molybdenum are all important, and the needs of improved pastures must be considered as well as those of cereals.

Journal of the Department of Agriculture, Western Australia, Series 4
In the late 1950's agricultural scientists in Western Australia became convinced that much of the improved pasture in the agricultural areas of the State was going to waste.
The results of the early trials resulted in many farm demonstrations of higher carrying capacities on improved pastures in southern agricultural areas.
Meadow Hay For The Dairy Herd, F E. Ryan
Meadow Hay For The Dairy Herd, F E. Ryan
Journal of the Department of Agriculture, Western Australia, Series 4
CONSERVATION is the basis of progress in dairy farming and the major form is meadow hay, but unfortunately relatively few dairy farmers give enough attention to the quality and quantity of this important feed.
